Toall'wkomt'tmay0011067111 C Be t i hat 1 J H SMI H a cltlzen of the United States, residing at MiddlewmButLer c untyalfihio, h e nve e certain new 'an' useful Improvements in Metallic Building Members, of which t e following is a specification. This invention pertains to the construction, from sheetmetal, of a metallic building member designed prmclpally for use 1n the construction of wall-work. While my invention is not limited in the respect to be devised with special walls of granaries. v

The inventio'nwill be readily understood I from the following description-taken in con-.

nection with the accompanying drawing in s which Figure 1 is an elevation ofa wall, assumed jas ametallic wall, embodying-my improved .the same, Fig. 2

studdingi and Fig. 2 a horizontal section of much less in proportion than would generally be the case inp'ractice.

Inthe drawin 1, indicates any suitable foundation to support the structure which is to embody my improved studding: 2,-the

studs, generally COIlSIdBI'Gd, which rest upon 'the foundation and are arranged in series,

circularor straight, and spaced apart such distance as is deemed preferable: 3, the

lain wall-members arranged. between studsand having their vertical edges engaging within the body of the studs, these wall-members being flat or horizontally curved according to whether the structure is to be circular or rectangular: 4, an empty wall-space, illustrated in Fig. 1: 5, sheet metal bent up to form the stud and engage the interior and exterior surfaces of the edges of the wall-members 3 and to form a stiffening rib: 6, the opposite edge portions of the sheet metal formin the stud, the outer extremities of these e ge portions engaging one surface of the wall-members 3: 7 portions of the stud materlal bent at 'rlght angles to portions 6 and crosslng the plane of wall-members 3: 8, ortions of the stud material bent outward and extending along that side of the wall material opposite stud portion 6, the outer extremities of these stud-portions 8 engagis on a very much larger scale than Fig.1, and in Fig. 1 the-distance between the studs is illustrated as being very the y from portions 7 ing that face of wall material '3 opposite the outer extremities of stud portions 6: 9, portions of the stud material in prolongation of stud portions 8 but bentback upon strengthening rib upon the side of the stud opposite ortions 6.

In pro ucin this sheet metal stud, a sheet metal strip 0 proper width may be taken and given its middle fold to form the rib 10, portions 9 being bent outwardly from opp o site sides of the rib, the portions 8 being then folded inwardly to give the double thickness, 8-9, bends 7 then being produced from the portions 8, opposite the Hi) 10, the

"portions 6 being bent outwardly from the portions 7.

The distance between the outer extremities of portions 6 and 8.will be such as to: accommodate, with suitable gripping effect, the

main wall material which is to fill the spaces between the studs. In the case of the main wall material being sheet metal, which will generallyrbe the case, the outer extremities of portions 6 and 8 may, if desired, be in contact with each other, so that the insertion of the sheet forming the main wall portion will require some springing apart of these extremities and produce more or less grip ping effect upon the wall-material. Itis my preference that the distance between stud portions 6 and 8 be more than the thickness of wall material which the stud is 'to receive, and that the outer extremities of these portions 6 and 8 be bent toward each other so as to form converging jaws for the gripplug of the main wall material, the outer side extremities of the stud thus being pro- 1 vided with wall-receiving jaws, so to speak.

An inspection of Fig. 2 will make it evident that wall-members 3 may be curved or straight, according to whether the structure is to be circular or rectangular, and also that, given a stud of the section illustrated in Fig. 2, its side members may be separated from each other, the union of portions 10 acting as a hinge so that the side members of the studs may be either in the same plane or at an lar relationship to each other.

I c aim A metallic building member consisting of an integral strip of sheet metal bent at its center fof width to form a forwardly out standing rib of double thickness, a portion bent sidewise from each of the thicknesses of said rib and at right angles thereto, said sidewise bent portions being then folded inwardly to the plane of said rib to form at each side of the rib a clamping member of double thickness, the inner thickness of said clamping members being then bent rear- Wardly in the plane of the rib and then bent outwardly sidewise, the edges of the metal resulting from the last bending coming opposite the extremities of said clamping members and forming second clamping members, said first-mentioned and second clamping members being adapted to receive a sheet of material between them, and the outer portions of the clamping members being bent into convergence with each other so as to engage the sheet only at the extremities of the clampin members, combined substantially as set orth.
